I've read several threads here about fixing permissions to unlock a drive that has become locked as readonly. I have tried running the suggested commands in terminal to no avail.
This is an external drive, worked fine before, never hooked to a pc - mac only all its life.
Now, get info shows that it is Read Only. The lock icon is not clickable.
Looking at permissions in terminal the world bit has a "t" rather than an "x" and it also has a "@":
when I try running the various permission changing commands I've found in different threads on this forum, no change is made and the feedback lets me know the disk is readonly. eg:
TRIED:
Tried running disk utility - repair permissions option greyed out. Tried verifying the disk. Got this error:
And now I can't access the disk at all.
I would appreciate any help.
Thank you so much.
